Abstract
Disclosed is a tool for the extrusion of fluid material from a flexible walled tube container such as a toothpaste tube. The tool comprises two clamping elements (1.4) having surfaces (1.5) held in close proximity to each other by resilient connectors (2.1). By applying a force so as to push connectors (2.1) towards each other the surfaces (1.5) are moved apart to allow the insertion of the end of the tube from which material is to be extruded. When the force is removed the resilient connectors cause the surfaces (1.5) to move towards each other and pinch the tube. Pushing the tool along the tube towards the outlet of the tube results in the contents of the tube being extruded. Alternatively the tube may be fed through a slit (1.2) in a first of the clamping elements to extrude the material. The empty portion of the tube may be passed through a second, wider, slit in a second of the clamping elements.
Description
Title: Multifunctional extrusion assistance tools
Technical field:
Product design, mechanical engineering
Description:
Very often, people find it difficult to extrude materia' from flexible containers (especia'ly tubes) which are nearly empty while at the same time wasting part of the fluid material that is present inside due to the fact that the tube is thrown away after emptying it, but however not extruding about 100% of the fluid material that was present inside. This is because there is no tool which is especially designed to assist the extrusion of flexible containers (especially tubes) and which guarantees that all of the material (about 100%) contained in the tube will be used for the uses of the user and hence will not be wasted.
A good example of that issue arises with toothpaste tubes.
The invention present on the appfication concerned consists of a tool which is designed to assist the user in extruding fluids out of flexible containers (preferably tubes) such as toothpaste tubes while simultaneously making sure that there is not material left behind the tool towards the rear of the tube.
The tool concerned in the application can also be used to seal one or more containers (preferably tubes or bags) simultaneously, hence acting as a multifunctional tool.
The tooling designs concerned can be a set of two clamping elements connected together by flexible connectors and/or a clamp-shaped tool which comprises a set of two clamping elements connected together by one flexible connector.

The extrusion assistance tool should preferably be made of a single piece component in order to minimise the number of parts as well as to minimise manufacturing costs.
The extrusion assistance tool comprises a set of two clamping elements [1.41 which are connected to each other by the means of two flexible connectors [2.2]. In order to maximise space profitability and multifunctionality of the two clamping elements [1.4], each is used for one or more specific functions.
One of the two clamping elements [1.4] comprises a narrow hollow channel (such as a slot or a slit) [1.2], which is designed to insert the rear part of a flexible container and pull the container upwards while keeping the damping element static or moving downwards, hence extruding the contents and minimising wasted material that may still be contained in the container. The other clamping element [1.4] however features a wider hollow channel (such as a slot) [1.1], which is designed to insert the rear of a flexible container downwards after inserting it upward through the hollow channel between the inner surfaces [1.5] of the two clamping elements [1.4], or through the narrow hollow channel (such as a slot or a slit) [i.2] comprised on one of the two clamping elements [1.4].
The outer surfaces [1.3] of the two clamping elements [1.4] comprise inner rounded profiles in order to maximise the ease of grabbing of the tool by the user's fingers.
The inner surfaces [1.5] of the two clamping elements [1.4] of the tool are positioned as close against each other as possible when the tool is submitted to no stress at all (relaxed) or to only compressive stresses applied on the outer surfaces [1.3] of the clamping elements [1.4].
When the tool's elements are in relaxed (unstressed) situation, the inner surfaces [1.5] of the two clamping elements should preferably be as close as possible to each other such that when an extrusion operation is performed. the user will have to keep the tool static and to apply a force only on the tool andlor the flexible container without having to push the inner surfaces [1.5] of two clamping elements [1.4] as close as possible to each other.
However, when the two clamping elements [1.4] are being pushed against each other, the inner surfaces [1.5] of the clamping elements [1.4] apply a load inwards each. The two clamping elements [1.4] are pushed against each other when a force is applied on the outer surfaces [1.3] of the two clamping elements [1.4]. This normally occurs when performing an extrusion operation.
The tool can be opened by displacing the two clamping elements [1.4] further away from each other. This is performed by applying a force on the element [2.1] comprised on each of the two flexible connectors [2.2]. The user can apply this force easily with the user's fingers.
When the user simultaneously applies a load on the two elements [2.1], the two clamping elements [1.4] are displaced outwards, hence increasing the distance between the inner surfaces [2.3] of the two clamping elements [1.4].
The user displaces the two clamping dements [1.4] away from each other when willing to insert a flexible container into the hollow channel between the two inner surfaces [2.3] of the tool's clamping elements [1.4] (prior of performing an extrusion operation), or to take out a flexible container from the hollow channel between the two inner surfaces [2.3] of thc tool's clamping elements [1.4] (after performing an extrusion operation).
The two clamping elements [1.4] are attached together by the means of a flexible connector [2.2], which will provide enough force to keep the two clamping elements [1.4] together thanks to its reaction force when anything would attempt to deform it when attempting to increase the distance between the inner surfaces [1.5, 2.3] of the clamping elements [1.4] and hence displacing the two clamping elements [1.4] away from each other.
The extrusion assistance tool comprises a narrow lateral hollow channel (such as a slot or a slit) [1.2] on one of its two clamping elements [1.4] in order to displace the material within the container, while also offering a wider hollow channel (such as a slot) [1.1] in order to insert emptied areas of the flexible container to be emptied.
The tool can comprise a double tooled configuration which consists of two sets of clamping elements [3.1] as comprised on Figures 1 and 2, but connected together by a thin flexible element [3,2] in order to keep the two tools connected together. This tooling configuration is designed in order to perform an extrusion operation by keeping the rear of the flexible container [4.1] tight between the surfaces [1.5, 2.3] of the two clamping elements [1.4] of one set of clamping elements [4.2] while pressing downwards on the other set of clamping elements [4.4] in order to extrude the material out of the container [4.1] through one of its sides [4.5] without leaving material in the part of the container [4.1] which is on top of the lower set of damping elements [4.4]. The thin flexible dement [4.3] is designed to be long enough in order for the user to push out all the material contained in the flexible container [4.1] until the lower set of clamping elements [4.4] reaches the lower end of the container [4.1], just on top of the container's pouring cavity [4.5]. The tube can be inserted either into the lower set of clamping elements' [4.4] fixed geometrised hollow channel (such as a slot or a slit) [1.2] or through the lower set of clamping elements' [4.4] hollow channel situated between the inner surfaces [1.5, 2.3] of its two clamping elements [1.4].
When performing extrusion operations by using the sing'e tool [5.3], only one set of elements [5.3] is being used.
When using only one set of clamping elements [5.3], the flexible container [5.4] can be initially inserted between the inner surfaces [1.5, 2.3] of the two clamping elements [1.4].
After passing the rear of the flexible container [5.4] between the two clamping elements [5.1], the flexible container [5.4] can be pulled and then inserted through the lateral hollow channel (such as a slot) [1.1], After passing the flexible container [5,4] through the lateral hollow channel (such as a slot) [5.2], the rear part of the flexible container can be pulled downwards in order to continue the extrusion operation efficiently and maximising the ease of perfoirning an extrusion operation for the user.
During the entire process described on the paragraph above, an extrusion operation can be performed, because as along as the container is being pulled into the hollow channel between the two clamping elements [5.1], the material contained in the container is being extruded out of the container through its exit cavity [5.5]. During the extrusion operation, it is recommended to keep the set of clamping elements [5.3] in a static position.
Another option when using the single set of clamping elements [6.2] is to insert the rear of the flexible container [6.1] into the hollow channel between the two inner surfaces [1.5, 2.3] of the two clamping elements [1.4] and then pulling on the rear of the flexible container upwards while simultaneously pushing downwards on the set of clamping elements [6.2].
However, in order to perform an extrusion operation, the flexible container [6.1] can be left static while pushing on the set of clamping elements [6.2], or vice versa. This is because any of the two operations will keep the material contained inside the container [6.1] under the set of clamping elements [6.2], and will hence displace the material in the container [6.1] down the flexible container [6.1] until reaching the container's exit cavity [6.3], where it will be extruded out of the container [6.1].
The set of clamping elements can also be configured in a clamp-shaped geometry. which comprises two clamping elements [7.3] attached together by a flexible connector [7.2].
The clamp-shaped tool hence features a set of two handles [7.1] which are designed to be pushed one against the other in order for the user to open the tool and hence to increase the distance between the inner surfaces [7.6] of the two clamping elements [7.3].
When the set of clamping elements is submitted to no stress (in a relaxed situation), the two clamping elements [7.3] are positioned as close to the other as possible, hence meaning that the inner surfaces [7.6] of the clamping elements [7.3] are positioned as close as possible to each other. When performing an extrusion operation, this deign would be more desirable in order for the user to be able to focus on displacing the tool or the flexible container without having to push on the outer surfaces [7,4] of the clamping elements [7.3] in order to maintain these tight to each other.
The outer surfaces [7.4] of the clamping elements [7.3] comprise inward circular profiles [7.4] in order to maximise the ease of grabbing the tool by the user's fingers.
The two clamping elements [7.3] are attached together by the means of a flexible connector [7.2], which will provide enough force to keep the two clamping elements [7.3] together thanks to its reaction force when anything would attempt to deform it when attempting to increase the distance between the iirner surfaces [7.6] of the clamping elements [7.3] and hence displacing the two clamping elements [7.3] away from each other.
Similarly to the extrusion assistance tool designs comprised on Figures i, 2 and 3, the design concerned comprises a narrow lateral hollow channel (such as a slot or a slit) [7.6] on one of its two clamping elements [7.3] in order to displace the material within the container, while also offering a wider hoflow channd (such as a slot) [7.7] in order to insert the already emptied areas of the flexible container to be emptied.
The extrusion assistance tool can comprise a double tooled configuration which consists of two sets of clamping elements [3.1, 8.1] as comprised on Figures 1 and 7, but attached together by a thin flexible element [3.2, 8.2] in order to keep the two tools attached together.
So, the tool can comprise two sets of clamping elements attached together as comprised on Figure 3, two sets of clamping elements as comprised on Figure 7 [8.3] which are attached together by a thin flexible element [3.2, 8.2], or two sets of clamping elements [8.1] which are attached together by a thin flexible element [8.2] as comprised on Figure 8. On Figure 8, the configuration comprises a set of clamping elements as compnsed on Figure 7 [8.3] attached to a set of clamping elements as comprised on Figure 1 [8.4] by the means of a thin flexible element [8.2].
On all configurations described on the previous paragraph, the two clamping elements [3.1, 8.1] which are attached to the thin flexible element [3.2, 8.2] (which connects the two sets of clamping elements [3.1, 8.1]), should be preferably positioned oppositely to each other. This is because if the two clamping elements [3.1, 8.11 are positioned oppositely to each other, said architecture will maximise the ease of use of the tool and will also avoid the use of unnecessaly additional material in the thin flexible element [3.2. 8.2].
The toofing designs concerned in this appfication also offers the muhifunctional option of using these as sealing tools for flexible containers such as bags. So, one or more bags can be sealed with the tools concerned. So, one container can be sealed with each tool as comprised on Figures 1 or 7. or at least two containers can be sealed with a double tooled configuration as comprised on Figures 2 or 8.
The most suitable type of flexible container in which the tooling designs concerned in this application should be used should be flexible tubes such as glue tubes and toothpaste tubes.
The tolling designs concerned in this application should be made of a material which is able to offer an acceptable strength and an acceptable ductility. Therefore, the most suitable material is a metal such as aluminium, a wood based material, or a polymer such as a polyamide or nylon, a polyester, a polyolefin such as polypropylene or polythene, ABS, a thermoplastic polyurethane, polyethylene tetrafluoride, or polyvinyichloride. The most recommended materials to be used would be polypropylene and polyvinylchloride not only because of their acceptable strength and ductility, but aiso thanks to the low costs that these offer.
The methods used to manufacture the tooling designs comprised in this application are material plate cutting methods (preferably laser cutting methods), laser sintering processes (preferably plastic laser sintering processes) casting processes (preferably investment casting processes), resin transfer moulding processes, or plastic injection mou'ding processes. The most recommendable manufacturing process would be laser cutting methods andlor plastic injection moulding processes thanks to the processes' low costs as weB as to the fact that the components should preferaHy be made out of a plastic material.
